Good morning Nick, great photos as always! I've spent a very happy hour or so going through my books but I can't find "Royal Swedish" anywhere. I don't think the glasses were made by Målerås, something says maybe Gullaskruf or Skruf, but why put "Royal Swedish" on them? The "Skandinaviska Etuifabriken" also did a set of shot glasses and cognac glasses with and without coasters but I couldn't see if they were labelled or not.Hope someone comes up with an answer...
